Sample Muscles, Neurovascular Anatomy of Head & Neck MCQs with answers
Sample MCQ #1
The muscles that cause constriction and dilation of the pupil are derived from:
AEctoderm
BEndoderm
CMesoderm
DNeural crest cells
Show Answer & Explanation ▾
✓ Correct Answer: A. Ectoderm
The musculature of the iris, including the sphincter pupillae and dilator pupillae, are derived from the ectoderm of the optic cup. Muscles of the iris (sphincter and dilator pupillae) Arrectores pilorum of skin Myoepithelial cells lining the ducts of sweat glands Reference - Textbook of Langman's, 12th Edition, Head and Neck Embryology Page number - 268
Sample MCQ #2
A 45-year-old man presents with a chief complaint of progressive hearing loss and dizziness. His history reveals a long career in the boxing industry, in which he sustained many blows to the head over his lifetime. You fear that he has incurred some cell loss in certain areas of his brain. Which of the following areas of cell loss would explain your patient's hearing difficulty?
ACorti ganglion
BPterygopalatine ganglion
CVestibular (Scarpa) ganglion
DSuperior cervical ganglion
Show Answer & Explanation ▾
✓ Correct Answer: A. Corti ganglion
The Corti ganglion, or spiral ganglion, is a group of nerve cells that convey the sense of hearing from sound sensory input from the individual organs of Corti within the cochlea. Cell loss in this ganglion would contribute to hearing loss. Reference: Textbook of Gray's Anatomy for students, 3rd Edition, Head and neck, page number - 987
Sample MCQ #3
Concerning the circuitry between mossy fibers, climbing fibers and cells of the cerebellar cortex, which of the following pairs both provide excitatory input?
Granule cell parallel fibers and mossy fibers both provide excitatory input. Reference: Textbook of Gray's Anatomy for students, 3rd Edition, Head and Neck, Page number - 841
Sample MCQ #4
What is the clinical importance of ligament of Berry?
AUseful in preserving RLN
BUseful in preserving ELN
CUseful in preserving IJV
DUseful in preserving EJV
Show Answer & Explanation ▾
✓ Correct Answer: A. Useful in preserving RLN
Berry's ligament constitutes a reliable anatomical structure for recognizing and preserving recurrent laryngeal nerves. P1 is the anatomical area with the greatest risk of recurrent laryngeal nerve damage during thyroidectomy, compared to P2 and P3.

Sample MCQ #5
Patient presenting with dysphagia, loss of sensory function from posterior 1/3 of tongue, absent gag reflex and trapezius muscle paresis was diagnosed with Vernet syndrome. Which of the following structure passes through posterior part of the involved foramen?
AInferior petrosal sinus
BCN 9, 10, 11
CSigmoid sinus
DSpinal accessory nerve
Show Answer & Explanation ▾
✓ Correct Answer: C. Sigmoid sinus
Vernet syndrome also known as Jugular foramen syndrome and it can be divided into three compartments: Anterior - Inferior petrosal sinus Intermediate - CN 9,10,11 Posterior - sigmoid sinus continuing as the internal Jugular vein. Reference: Textbook of Gray's Anatomy for students, 3rd Edition, Head and neck, Page number- 423 and 459
Sample MCQ #6
A patient presents with dysarthria, difficulty swallowing and difficulty moving the tongue. When patient is asked to protrude tongue, the tongue deviates to one side. Patient underwent surgery 5 days back and due to breathing complication, patient gone through excessive traction of laryngoscope with hyperextension of head and neck during intubation. What is injured here ?
APost operative hypoglossal nerve palsy
BPost operative facial nerve palsy
CIdiopathic trigeminal nerve palsy
DIdiopathic Glossopharyngeal nerve palsy
Show Answer & Explanation ▾
✓ Correct Answer: A. Post operative hypoglossal nerve palsy
Damage to the hypoglossal nerve causes paralysis of the tongue. Usually, one side of the tongue is affected, and when the person sticks out his or her tongue, it deviates or points toward the side that is damaged. Hypoglossal nerve palsy is often encountered as a complication of nerve injury in head and neck surgery, may result from tumors, strokes or neurological diseases like ALS. Iatrogenic hypoglossal nerve palsy especially after airway management in general anaesthesia and suspension laryngoscopy.

Sample MCQ #7
A patient presents with blurred vision, confusion, memory loss, Numbness in left side of body, problem with thinking, reasoning, memory and speech. Further examination reveals carotid artery stenosis. Which of the following branches of internal carotid artery will not be involved in this case ?
ABranch to the trigeminal ganglion
BMeningeal branch
CBranch to cavernous sinus
DCorticotympanic branch
Show Answer & Explanation ▾
✓ Correct Answer: D. Corticotympanic branch
There are seven segments of internal carotid artery in the Bouthillier classification: C1: cervical segment C2: petrous (horizontal) segment C3: lacerum segment C4: cavernous segment C5: clinoid segment C6: ophthalmic (supraclinoid) segment C7: communicating (terminal segment) The cavernous segment has - Branch to trigeminal ganglion Meningeal branch Branch to cavernous sinus Hypophyseal branch Reference: Textbook of Gray's Anatomy for students, 3rd Edition, Head and neck, Page number - 281
Sample MCQ #8
An occlusion of which artery would result in a loss of voluntary motor function and an oculomotor nerve palsy?
APosterior inferior cerebellar artery(PICA)
BPosterior communicating artery
CMiddle cerebral artery
DPosterior cerebral artery
Show Answer & Explanation ▾
✓ Correct Answer: D. Posterior cerebral artery
An occlusion of the posterior cerebral artery would result in a loss of voluntary motor function and an oculomotor nerve palsy. The posterior cerebral artery supplies blood to the occipital lobe of the brain, which is responsible for visual processing. When this artery is blocked, it can lead to a loss of motor function and paralysis on one side of the body, as well as damage to the oculomotor nerve, which controls eye movement.
